As an embodiment of the application, in order to complete the installation of the fastener and the shaping of the railway ballast at two sides of the track, the operation method of the continuous sleeper-changing operation train further comprises the following steps:
step six, installing a fastener after the track falls to the sleeper by the fastener installation device 25 at the bottom of the power vehicle D;
And step seven, the side slope shaping device 26 at the bottom of the power vehicle D shapes the railway side slope ballasts.
The continuous sleeper replacement operation train and the operation method provided by the embodiment of the application can realize the replacement of multiple sleepers at one time under the condition of not sawing the track, realize the integrated continuous operation of the disassembly of the fastener, the replacement of the sleeper, the installation of the fastener and the transportation of the sleeper under one skylight point, and greatly reduce the subsequent construction cost and the construction time because the continuous sleeper replacement operation train and the operation method can not cut the track any more for sleeper replacement.
In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the drawings are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.
Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.
In the present application, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed, mechanically connected, electrically connected, or in communication with each other, directly connected, indirectly connected via an intervening medium, or in communication between two elements or in an interactive relationship between the two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.
While preferred embodiments of the present application have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the application.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present application without departing from the spirit or scope of the application. Thus, it is intended that the present application also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
